SIMATIC ET 200pro
Figure 4-9
SIMATIC ET 200pro FC‑2 inverters only have one internal fail-safe digital input. You require
the F‑RSM module if you wish to control the ET 200pro FC‑2 safety functions directly via a
sensor.
The F‑RSM module evaluates the sensor, and switches the "F0 rail" in the backplane bus of
the ET‑200pro system. The F0 rail selects a safety function in the inverter via the internal fail-
safe digital input.
Additional ways of installing F‑RSM module are provided in the Internet:
